Patent GB-495122-A (GB)
Title: Improved apparatus for transporting and handling refuse and like containers
IPC: B65F3/00
Filed: 1937-06-16
Abstract: 495,122. Loading refuse containers on to vehicles &c. DENNIS BROS., Ltd., and DAWES, H. W. June 16, 1937, No. 16689. [Class 78 (iv)] [Also in Group XXXII] A vehicle or trailer carries a number of parallel runways 11 up which refuse containers 14 are hauled from a position on the ground as seen in Fig. 4, by means of a cord 19 passing to a hand or power operated winding drum. A series of these drums, one for each runway, are selectively clutched to a common driven shaft rotated by hand through chain gearing 22. Means are provided, independent of the winding mechanism, for locking the containers on the runways in two positions, one, for transit, in which the container is carried laterally wholly within the wheel base, and the other, for discharging, in which it slightly overlaps the lower edge of the runway so that discharge can take place by gravity through the opened end door 32. Each container has a pair of longitudinal skids 17 and a pair of parallel cross bars which operate the locking- mechanism shown in Fig. 5. The latter comprises levers 26, 28, at different levels on the runway. Contact of the cross-bar of an upwardly-moving container with the lever 26 trips the latter in passing the spring 27 restoring it. Continued upward movement then trips the lever 28. This, through the link 30, swings lever 26 so that the spring 27 passes the dead centre and retains the lever below the level of the cross-bars. The second bar on the container then contacts the projection 31 and re-sets the lever 26 in passing. In operation, in raising a container, the first cross-bar trips lever 26, and then lowers it on striking lever 28, while the second bar re-sets the lever 26. The raising is stopped before the second bar reaches the lever 28. On lowering the container slightly, the upper cross-bar rests against the upper bars 26 which act as stops. This is the transport position. On raising the container till the top bar trips the top lever 28, the top lever 26 is lowered, and the container can then be lowered. In lowering, the bottom cross-bar contacts 31 and re-sets the lever 26 to catch the top cross-bar and hold the receptacle in the dumping position. A further slight raising to trip the lever 28 allows complete lowering for grounding the emptied receptacle. The containers are provided with trunnions which can be engaged by the hooked axles of a lever hand truck for carrying the receptacles to and from the vehicle. Provision is made for carrying the hand-truck on the vehicle.

Title: Mechanism for cutting sheets of material from a continuous strip, such as a roll
IPC: B65B41/16
Filed: 1950-07-05
Abstract: 692,796. Feeding webs; cutting &c. apparatus. AYERS, F. L., and GRIMSHAW, J. P. Aug. 14, 1951 [July 5, 1950], No. 16797/50. Class 100(i) [Also in Group VIII] The feed rollers 1, 2 of a mechanism for cutting sheets of variable length from a roll or strip of material, for delivery to a parcelling, printing or other machine, are driven through a one-revolution clutch 10 on a main shaft 11, a chain drive 8 and a dog-clutch 6, the clutch being held engaged by springs 29 until, after the desired length of sheet has been fed, it is disengaged by a lever 18 rocked by a face cam 20 on the main shaft; the cam comprises two parts with side projections 21a, 22a which can be angularly adjusted relative to each other to extend or decrease the lift period of the cam and thus vary the period during which the drive is disengaged. The rollers are geared together and have grooves 2a for a metal comb which prevents the material adhering to the rollers. The onerevolution clutch 10 is controlled from the parcelling or printing machine so that the sheets are delivered in synchronism with the operation of the machine and a disc brake 27 prevents overrun of the rollers after the clutch is disengaged. At the end of each revolution of the shaft 11, a pivoted cutting blade 35 is lowered to cut the stationary material against a fixed blade 39 by a projection 32 on a cam 31 actuating a lever 34 having a roller and slot connection 37 with the blade 35. The Provisional Specification also describes adjustment of the cams by a screw pin engaging an aligned pair of vernier-spaced holes in each cam.

Title: Preparation of Cobalt/Tungsten Carbide Mixtures
IPC: C01B32/949
Filed: 1968-04-08
Abstract: 1,173,109. Making tungsten carbide-cobalt. E.I. DU PONT DE NEMOURS & CO. April 8, 1968 [April 10, 1967], No. 16812 / 68. Heading C7D. An intimate mixture of tungsten carbide and cobalt is made by reducing a source of tungsten in a molten salt bath in the presence of enough carbon to convert all the tungsten to tungsten carbide and introducing a source of cobalt into the bath before during or after the formation of the tungsten carbide. Suitable tungsten sources are cobalt tungstate and para-tungstate (suitable also as cobalt sources), tungstic oxide and compounds which yield tungstic oxide on heating such as tungstic acid and its salts including calcium and cobalt tungstate, tungsten chlorides and finelydivided tungsten metal. Suitable cobalt sources are the tungstates already specified, cobalt metal, cobalt oxide and compounds which yield cobalt oxide on heating such as cobalt carbonate and formate, cobalt sulphide and cobalt chloride. Suitable carbon sources are carbon black and calcium carbide. The latter is suitable as a reducing agent owing to its calcium content: other suitable reducing agents are metallic calcium (preferred), and gaseous hydrogen. Suitable molten salts are calcium chloride, and sodium, potassium and lithium chlorides. In the example, co-precipitated tungstic oxide-cobaltic oxide are added with fine carbon and calcium metal to molten calcium chloride under argon, and the product then washed. The products may be hot-pressed to form cutting tools.

Title: Improvements in arrangements for the control of railway trains at junctions and the like
IPC: B61L19/06
Filed: 1928-06-11
Abstract: 310,223. Underwood, W. J. June 11, 1928. Drawings to Specification. Electrical systems, non-automatic. -For controlling traffic at junctions, crossings or like places the track is divided into insulated sections and for each section there is provided a switch which normally is in a neutral position but can be set, by the operator, to an initiating position from which it returns to the neutral position as soon as it is released and can be set also to permissive position in which it remains until reset manually. To set a track through the area controlled from the switchboard, the switches relative to conflicting track sections are set to permissive position and that for the converging or diverging tract to be, traversed into its initiating position. Each switch has a series of permissive positions corresponding to the several tracks with which its relative track may conflict. The points-motor relay-circuits, signal relay circuits and trainstopping trip circuit are controlled by the initiating switch in conjunction with a shunt circuit which is prepared by the permissive switches and includes the various track rails of conflicting tracks. By this means a track cannot be cleared for a train if another train occupies a conflicting section. The continuity of a circuit which includes one rail of the whole of the tracks controlled is continually tested by a relay which controls the common return lead of the operating circuits.

Filed: 1920-06-25
Abstract: Terpenes, or certain derivatives, such as terpineol or rosin, are heated with sulphur to produce brittle solids or semi-solids according to the duration of the heating; sulphuretted hydrogen is evolved.  In an example, equal parts of oil of turpentine and sulphur are heated together for three hours at a temperature rising from 150 DEG -200 DEG  C., yielding a neutral brittle mass soluble in turpentine, toluene, and xylene; the quantity of gas evolved may serve as a check on the progress of the reaction.  The products form non-colloidal solutions and may be used, either alone or in toluene, xylene &c. solution with or without addition of rubber, for coating or impregnating materials; they may also be vulcanized on to or with rubber and can be moulded.  If a semi-solid product is employed, further heating effects conversion to the harder products; for example, if mixed with wood pulp and heated in a press, a hard solid mass results.
